IT is well established that an increase in the intracellular concentration of ionized calcium after excitation in the membrane is the key factor for initiation of contraction of various types of ...

Researchers were able to control heart muscle function in a new way after discovering the previously unknown role of two enzymes in heart muscle contraction. Although in the early stages, the research ...

The contractile responses of esophageal smooth muscle (SM) induced by platelet-activating factor (PAF) involve the activation of L-type voltage-dependent calcium channels (L-type VDCCs), ...

IT is believed that muscle contracts or relaxes depending on the concentration of calcium in the sarcoplasm: when the concentration rises to some required level the muscle contracts; when it falls ...

Calcium is usually associated with foods such as dairy and leafy vegetables, but adding some herbs and spices to your foods can help up their calcium content.

The ability to modify the intracellular concentrations of divalent calcium ions is vital to normal cell functioning. In the cells of the cardiac muscle, calcium ions play a crucial role in coupling ...

Together, these findings suggest that ferulic acid can act as a natural regulator of intestinal motility. By reducing ...

Vitamin D deficiency, rampant in India at 70–90% of the population, adds another layer of trouble by curbing calcium ...

Evidence from randomized trials suggests that calcium supplements may not significantly reduce fracture risk in ...

Researchers engineered mice with a mutation (E3896A) in the RyR1 calcium-binding site, eliminating calcium-induced calcium release (CICR) without affecting depolarization-induced calcium release. The ...
